From Philosophy About Truth To The Wisdom Of EPA Models About Emissions

Rereading Alfred North Whitehead, one of my favorite philosophers, provides the context for the current debate over the wisdom of using the EPA’s amended transportation emissions model (Motor Vehicle Emission Simulator, or MOVES) for state-by-state analysis. He once indicated that, “There are no whole truths; all truths are half-truths. It is trying to treat them as whole truths that plays the devil.”

I am uncertain about Whitehead’s skepticism, if treated as an absolute. However, it does give pause when judging the use of an amended MOVES model, based mostly on advocacy research by the nonprofit group, the Coordinating Research Council (CRC). The CRC is funded by the oil industry, through the American Petroleum Institute (API), and auto manufacturers.

CRC was tasked by the EPA with amending MOVES and applying it to measure and determine the impact of vehicular emissions. The model and related CRC analysis was subject to comments in the Federal Register but the structure of the Register mutes easy dialogue over tough, but important, methodological disagreements among experts. Apparently, no refereed panel subjected the CRC’s process or product to critique before the EPA granted both its imperator and sent it out to the states for their use.

I am concerned that if the critics are correct, premature statewide use of the amended MOVES model will mistakenly impede development and use of alternative transitional fuels to replace gasoline, particularly ethanol, and negatively influence related federal, state and local policies and programs concerning the same. If this occurs, because of apparent mistakes in the model (and the data plugged into it), the road to significant use of renewable fuels in the future will be paved with higher costs for consumers, higher levels of pollutants and higher GHG emissions.

With some exceptions, the EPA has been a strong supporter of unbiased, nonpartisan research. Gina McCarthy, its present leader, is an outstanding administrator, like many of her predecessors, like Douglas Costle (I am proud to say that Doug worked with me on urban policy, way, way back in the sixties), Russell Train, Carol Browner, William Reilly, Christine Todd Whitman, Bill Ruckelshaus and Lee Thomas. No axes to grind; no ideological or client bias…only a commitment to help improve the environment for the American people. I feel comfortable that she will listen to the critics of MOVES.

The amended MOVES may well be the best thing since the invention of Swiss cheese. It could well help the nation, its states and its citizens determine the truths or even half-truths (that acknowledge uncertainties) related to gasoline use and alternative replacement fuels. But why the hurry in making it the gold standard for emission and pollutant analysis at the state or, indeed, the federal level, in light of some of the perceived methodological and participatory problems?

Some history! Relatively recently, the EPA correctly criticized CRC because of its uneven (at best) analytical approach to reviewing the effect of E15 on car engines. Paraphrasing the EPA’s conclusions, the published CRC study reflected a bad sample as well as too small a sample. Its findings, indicating that E15 had an almost uniform negative impact on internal combustion engines didn’t comport with facts.

The CRC’s study of E15 was, pure and simple, advocacy research. CRC reports generally reflect the views of its oil and auto industry funders and results can be predicted early on before their analytical efforts are completed. Some of its reports are better than others. But overall, it is not known for independent unbiased research.

The EPA’s desire for stakeholder involvement in up grading and use of MOVES to measure emissions is laudable. However it seems that the CRC was the primary stakeholder involved on a sustained basis in the effort. No representatives of the replacement fuel industry, no nonpartisan independent nonprofit think tanks, no government-sponsored research groups and no business or environmental advocacy groups were apparently included in the effort. Given the cast of characters (or the lack thereof) in the MOVES’ update, there’s little wonder that the CRC’s approach and subsequently the EPA’s efforts to encourage states to use the amended model have been and, I bet, will be heavily criticized in the months ahead.

Two major, well-respected national energy and environmental organizations, Energy Future Coalition (EFC) and Urban Air Initiative, have asked the EPA to immediately suspend the use of the MOVES with respect to ethanol blends. Both want the CRC/MOVES study and model to be peer reviewed by experts at Oak Ridge National Lab (ORNL), and the National Renewable Energy Lab (NREL). I would add the Argonne National Laboratory because of its role in administering GREET, The Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation Model. Further, both implicitly argue that Congress should not use the CRC study and MOVES until the data and methodological issues are fixed. Indeed, before policy concerning the use of alternative replacement fuels is debated by the administration, Congress and the states both appear to want to be certain that MOVES is able to provide reasonably accurate estimates of emissions and market-related measurements, particularly with respect to ethanol and, as Whitehead would probably say, at least provide half-truths, or, as Dragnet’s Detective Jack Webb often said, “Just the facts, ma’am,” or at least just the half-truths, nothing but at least the half-truths.

What are the key issues upsetting the critics like the EFC and the Urban Air Initiative? Apart from the pedigree of the CRC and the de minimis roles granted other stakeholders than the oil industry, the CRC/MOVES model, reflects match blending instead of splash blending to develop ethanol/gasoline blends. Sounds like two different recipes with different products — and it is. Splash blending is used in most vehicles in the U.S. and generally is perceived as producing less pollution.

Let’s skip the precise formula. It’s complicated and more than you want to know. Just know that according to the letter sent to the EPA by the EFC and Urban Air Quality on Oct. 20th, the use of match blending requires higher boiling points for distillation, and these points, in turn are generally the worst polluting aromatic parts of gasoline. It noted that match blending, as prescribed by the MOVES, results in blaming ethanol for increased emissions rather than the base fuel. There is no regulatory, mechanical or health justification for adding high boiling point hydrocarbons to test fuels for purposes of measuring changes in vehicle tailpipe emissions, when ethanol is part of the fuel mixture. Independent investigations by automakers and other fuel experts confirm that the use of match blending in the study mistakenly attributed increased emission levels to ethanol rather than to the addition of aromatics and other high boiling hydrocarbons, thereby significantly distorting the model’s emission results. A peer-reviewed analysis, which will be published shortly, found that the degradation of emissions which can result is primarily due to the added hydrocarbons, but has often been incorrectly attributed to the ethanol.

The policy issues involved due to the methodological errors are significant. If states and other government entities, as well as fuel supply chain participants, use the model in its present form, they will mistakenly believe that ethanol’s emissions and pollutants are higher than reported in study after study over the past decade. The reported results will be just plain wrong. They will not even be half-truths, but zero truths. Distortions in decision making concerning the wisdom of alternative transitional replacement fuels, particularly ethanol, will occur and generate weaker ethanol markets and opportunities to build a strategic path to renewables. The EPA, rather than encourage use of the study and the model, should pull both back and suggest waiting until refereed review panels finish their work.

Ruminations on oil donations, foreign nations and replacement fuels

The “Old Gray Lady,” The New York Times, did it again….its recent article indicating the extent of government funds from foreign countries supporting so-called independent think tanks and universities in the U.S. was enlightening and was also clearly in the public interest. Most of us policy wonks suspected or knew what the Times indicated on September 7. “More than a dozen prominent Washington research groups have received tens of millions of dollars from foreign governments in recent years while pushing United States government officials to adopt policies that often reflect the donors’ priorities…” The money is transforming the once-staid, think-tank world into a muscular arm of foreign government’s lobbying in Washington. And it has set off troubling questions about intellectual freedom — some scholars say they have been pressured to reach conclusions friendly to the government that is financing the research.” In this context, NATO, European, Middle East and Asian nations (e.g., Norway, Germany, Qatar, Saudi Arabia, United Arab Emirates, Japan, etc.) have been visible funders according to the Times and other media..

Before readers become holier than thou about the perception of perversion in foreign governments that link their support to what they want done regarding research and lobbying (implicit, if not explicit), they should know that the grant system in the U.S., in general, is not free of, at times, donor efforts to influence and/or sometimes pressure, whether it involves foreign governments, all levels of government in the U.S, business or foundation grants. Both have been and will remain the way of doing business.

I suspect attempts to influence or pressure research institutions or scholars are sometimes worse in social science research than in the sciences or engineering, where data, analysis and results can often claim at least some visible and quantifiable correlation or causation relationships. A donor’s ideological commitments also may predetermine and lessen the need for donors to try to negotiate the outcomes of grants or gifts. Not many liberal academics will apply for research money from the Koch Family Foundations, not many conservatives will likely go to the George Soros Open Society Foundations (OSF) for money.

Life is complicated for donors and recipients. Free speech and the free flow of ideas are embedded in the U.S. creed and the nation’s constitution. Truth in advertising in research grants and their products, a mythological spin-off, is often muted by the overwhelming influence and importance of money and the need for it, in light of fund shortages. However, the American public, for the most part, cannot easily separate the respected status of the Brookings Institution, the University of California, the Center For Global Development, the Center for Strategic and International Studies, etc. from their willingness to accept what seem clearly donor advocacy grants and subsequently to participate in what appears, to many, to be advocacy research and lobbying. The involved leaders, not always the researchers, of recipient institutions will deny the fact that research money sometimes comes with a price concerning legal, moral and often spoken words in grantor testimonials or contracts concerning obligations to search for the truth and increase wisdom concerning policy and program options.

Oil and oil-related companies and Middle Eastern nations seem now to be among the biggest givers and perhaps receive the biggest “take back” benefits. They fund schools and centers as well as analyses in and at major universities and independent think tanks, both within and outside universities. They have also funded “independent” scholars, chairs and specific RFPs (Request for Proposals) describing general and sometimes relatively specific areas of energy or transportation and fuel-related research. Significant oil and foreign money for policy-related research is also funded through third-party groups, which often mask the source of donations. Donors, understandably, expect benefits from supported research — at least consistency with and, in some cases, advocacy for their economic, social welfare and environmental objectives.

Perhaps one of the more egregious relationships concerning policy or program research involved the Coordinating Research Council (CRC), generally a mouthpiece of and also funded by the oil and automotive industry. Its relatively recent study debunking of E15 reflected the views of their sponsors — again the oil and auto industries. It indicated that E15 significantly harmed engines of many vehicle classes. The study was legitimately criticized by the EPA and others concerning methodology and content. Indeed, it and its implications concerning use of E15, was refuted in part or whole by the EPA’s more extensive analyses, by the National Renewable Energy Laboratory (NREL) and by other respected groups and individuals, some even associated with the auto industry. CRC’s efforts stimulated analyses and similar findings by groups like AAA— again based on even weaker methodology and unknown funding (likely mostly membership dues). Critics have pointed to AAA’s tenuous policy links to members and its long-time support by and of the auto and oil industries. Remember, more cars result in more gasoline use and increased ownership secures more AAA memberships.

Forget the legitimacy or illegitimacy of the proponents and critics of research concerning E15, or for that matter E85. At most times, policy choices and behavior are not based on perfection concerning data and analysis.

What concerns me the most is the predominance of oil and its friends’ money and the lack of transparency concerning funding sources and grant and gift requirements or constraints — both informal and formal.

Like the Times, I am also concerned about the dividing line between education and lobbying concerning grants and gifts provided by oil companies and, foreign nations. Lobbyists are required to register as such. Most think tanks and universities do not see themselves as lobbyists and do not register.

Industry, some foundation and even government-supported research grants sometime come with strings attached. Even if they didn’t, the results of paid research into complex issues are generally not conclusive and can be helpful in stimulating dialogue, if it’s matched by research initiatives funded by donors with different perceptions. Bad, or mediocre research funded by advocates, like speech, shouldn’t be countered by censorship, but by efforts to execute better research and by initiatives to provide to policymakers and the public with countervailing views and analysis to generate dialogue and debate.

I am not a purist. There is no chance in hell that the basic system of what I call advocacy grants and gifts now in existence will end. But public policymakers should insist on transparency as to funding sources and research methodology. Key advocacy studies likely to affect public sentiment and decision maker views concerning replacement fuels and gasoline should be granted, at least some form of even informal refereed reviews. If I could figure out an easy way to do it, I would define alternatives that would provide some reasonable equivalency concerning research funding. They would assure Americans that all key replacement fuel options are examined fully and are compared to gasoline. The research on replacement fuels should not be submerged by foreign nation or internal U.S. oil interest funding. But I don’t get paid enough nor am I smart enough to think this one through, at least until the next column. Maybe you can help me? Paraphrasing my favorite oil scholar, Socrates, unexamined studies funded without independent review, only by the oil industry or its Middle East friends and colleagues, are often not worth having or debating. Peace.
